RIVETING-MACHINE.

EQPECIFICATION forming part of Letters Patent No. 377,051, dated January 31, 1888.

Application tiled January3,1887.

To ctZZ whom, it may concern:

Be it known that we, JOHN L. SAXE, of \Vaterbury, in the county of New Haven and State of Connecticut, NORMAN M. SEELYE, of Cambridge, in the county of Middlesex and State of Massachusetts, and FREDERICK W. COY, of Boston, county otSuft'oll ,a11d State of Massachusetts, have invented certain new and useful Improvements in lliveting-Hachines, of which the following is a specification.

This invention relates to machines for inserting rivets in two or more superposed layers to be united and supplying burrs or washers to said rivets, the rivets being inserted from one side of the work and the burrs placed on the opposite side, the rivet-shanks being inserted through the holes in the burrs and upset therein, and thus united to the burrs.

In riveting machines as heretofore con structed the organization has been such that the operations of making the holes for the rivets, inserting the rivets in said holes, and upsetting the ends of the rivets have required not less than two rotations of the drivingshalt, thus making the operation slower than is desirable, and the rivets have been inserted in the work from the upper side thereof, so that the operator has been obliged to turn the work to see if the burrs have been properly engaged with the rivets.

Onrinvention has for its object to enable the operations of punching the holes and of inserting and upsetting the rivets to be performed duringa single rotation ofthedrivingshaft, and thus make the operation of the ma chine more rapid than heretofore.

The invention also has for its object to provide an organized machine capable of supplying the burrs to the upper side of the work and of inserting the rivets from the lower side, so that the upset ends of the applied rivets will always be in view of the operator.

To these ends our invention consists in the improvements which we will now proceed to describe and claim.

The same letters of reference indicate the same parts in all the figures.

In the drawings, (t represents the supporting-frame, having a bed or table, I), and an overhanging arm or goose-neck, c. In the arm 0 is located the vertical han'imer-carrying slide d, which is provided with ahammer, 0, adapted to upset the ends of the rivets, said slide being forcibly depressed by a spring, f, composed in this instance ofa series of superposed leaves. One end of said spring bears 011 a 8 part of the frame and its other end on the hammencarryingslide d. Ayoke, pivotally connected to the goose-neck, embraces the spring and has a screw, it, which bears upon the upper side of the spring and is capable of regulating the force thereof.

In the frame, below the worksupporting table I), are two vertical slides, ij, located side by side in a vertical guide in the frame. To

the upper end of the slidez' is affixed an awl 9 or punch, k, to perforate the work. The slide 2' is reciprocated vertically by a cam, Z, Fig. 1, on the driving shaftm and a lever, n, pivoted at 0 to the supporting-frame ol' the machine, the rear end of said lever being held by a spring, p, against the cam I, while its opposite end enters a slot, q, Fig. 2, in the lower portion' of the awl-carrying slide 13. The rotation of the drivingshaft causes the cam l to oscillate the lever n, which in turn raises and low.- ers the slide i and the awl or punch. The awl in rising passes through an aperture in the work-plate and through the material into a burr or washer, which is held against the upper side of the work by means hereinafter described.

The slide j, located beside the awl-carrying slide, has on its upper end a transverse head, i, on which are horizontal dovetail guides ua. Fitted to slide between said guides is a block, '0, on which is an anvil, 'ug, upon which the rivets to be inserted are placed by means hereinafter described. The anvil-carrying slide bears on a cam, a, on the driving-shaftm, and is raised and lowered by said cam. The block 1), which directly supports the anvil, rises and falls with the slide j, and is reciprocated horizontally by means of a cam-groove, b, in a disk, 0, on the vertical shaft 65, which communicates motion from the driving-shaft m to the shaft e in the goose-neck and a sliding rod, f, having at one end a stud entering the cam-groove b, and connected at its other end with the anvil-block 'u by means of a vertical stud, g,projecting downwardly from said block into an orifice in the rod f, said connection enabling the anvil-block to rise and fall without the necessity of vertical movement of the The anvil w is provided with two jaws, h h, which are pivoted to the sides of the anvil at i i, Fig. 11, and are capable of meetingover the anvil to grasp the shank of an inverted rivet, the head of which rests on'the anvil, Fig/l0. The meeting edges of said jaws are provided with cavities jj, Fig.11, formed to receive the rivet-shank, and said edges at one side of said cavities are flared outwardly from each other to form a tapering slot leading to the cavities, the outer end of said slot being a fixed arm, 9%, attached to the frame, and are arrested by said arm, so that the jaws open and release the rivet, as shown in Fig. 11.

0 represents the rivet-hopper, supported at the rear of the machine.

extends a raceway or channel, 19, through which the rivets pass from the hopperto the devices'which insert them in the material. Said raceway is composed of a bottom plate and two parallel guides on the upper surface From said hopper of said plate, said guides being separated by a space of sufficient width to permit the passage between them of the shanksof the rivets, while their inner edges are beveled or undercut to accommodate the heads of the rivets, the surfaces of said heads sliding on the bottom plate. The rivets therefore pass from the hopper to the inserting devices in an inverted position and are inserted in the material in the same position, as hereinafter explained.

The portion of theraceway leading from the hopper is inclined, so that the rivets pass from the hopper by gravitation, while the remaining portion of the raceway is substantially horizontal, so that the rivets are moved horizontally under the work-supporting,tab1e and are kept near the plane of said table, and therefore require to be elevated by the anvil only a short distance to be inserted in the work, as hereinafter described.

The rivets in the horizontal portion of the raceway are moved positively forward by a feeding device, hereinafter described, though other equivalent means could be employed. \Ve prefer to use as said feeding device a reciprocating slide, q, connected by an arm, r, to the reciprocating rod f, which reciprocates the rivet-supporting anvil.

The feeding-slide q istimed to move the rivets exactly as fast as they are inserted in the work. The rivets are transferred from the outer end of the horizontal portion of the raceway to the anvil w by a horiiontally-moving slide, 3', which is reciprocated in a guide, t, crosswise of the raceway by means of the cam a on the drivingshaft, a lever, to", pivoted at v to an car on the frame a, a rod or slide, 20, interposed between the cam a and the lower end of the lever a, and a spring, a which presses the lever so as to normally force its upper end away from the anvil. The upper end of the lever to is engaged with the rivet-transferring slide by entering a slot in said slide, so that when oscillated by the combined action of the cam a and spring a it reciprocates the transferring-slide 8. When said slide is drawn back, the last rivet in the raceway p is forced out in front of the end of the slide by the rivetfeeding device q, so that when the slide 8 is too forced forward it pushes said rivet through a short lateral guide, b communicating with the outer end of the raceway, and inserts it between the jaws h it, its head resting on the anvil and its shank projecting upwardly, as shown in Fig. 10. y I

0 represents a slide located beside the hammer-carrying slide in the goose-neck c and in contact therewith. The slide 0 has at its lower end an offset tubular throat, cl", Fig. 6, into which the hammer e projectst V I 6 rep resents a sleeve adapted to slide on said throat and extending below the same, said sleeve being provided with spring-fingers f f, formed to receive and hold between them a burr or washer, 9, Fig.8, which is inserted be tween said fingers by a feeding-slideflfi, reciproeated, by means hereinafter described, across the bottom of a vertical reservoir, 1', adapted to hold a vertical column of burrs. The burrholding sleeve is pressed downwardly by a spring, j", its downward movement being limited by a headed pinflv", Fig. 9, attached to its upper end and sliding through a socket in a collar, Z, rigidly attached to the throat (1 the head of the pin 76" bearing against the upper surface of the collar P. The sleeve 6" is therefore capable of yielding upwardly when pressed against the work, as hereinafter described,thus accommodatingitself to the thickness of the work.

The slide 0 supporting the burr-holding sleeve, is reciprocated vertically by a camgroove, m in a disk, of, on the shaft 6, journaled in the arm or goose-neck. \Vhen the slide 0 is raised by said cam-groove, its offset lower end bears on the lower end of the hammer slide (1 and raises the latter until an arm, 0", on the hammer-slide is engaged by aspringactuated latch, 12 on a rock-shaft, q", said lat-ch engaging automatically with the arm 0 and holding the hammerslide elevated until the latch is moved to disengage it from said arm and release the hammer-slide by contact of a stud, r Figs. 2 and 3, on the rear side of the disk a with an arm, 8, on the rock-shaft q". A spring, on the rock-shaft q gives the latter a tendency to turn in the direction required to engage the latch 12" with the arm of the hammer-slide d.

The burrs are supplied to the reservoir 2' from a chute or tray, 11/ whichis supported at its rear end by a bracket, 12", attached to the gooseneck c. Said chute or tray is attached to the bracket o", and is vertically adjustable by means of a screw, w", working in the outer end of the bracket 22 In this way the inclination of the hopper may be varied.

The burrs are caused by thejar attending the operation of the machine to slide down the inclined chute or tray to" and drop from thence into the reservoir The slide h that feeds the burrs from the reservoir t to the holdingfingers f f on the sleeve 6", is reciprocated horizontally in guides on the bracket '0 by means of a lever, (r, pivoted at b to an ear on the goose-neck, and having one arm jointed to the slide h and its other arm arranged in the path in which a stud, 0 on the rear side of the disk 11' travels. \Vhen said stud encounters the lever a it turns the latter on its fulcrum, so that the lever pushes the slide it forward and causes its forward end to move the bottom burr from the column in the reservoir t and push it under a spring-depressed presser-foot, e, to the springfingers of the sleeve 6 The slide h is of greater thickness than a burr g, and has in its upper surface at its forward end a recess of a depth nearly or quite equal the thickness of a burr. Thelowest burr in the column drops into said recess and remains in it until it is thrust between and grasped by the spring-fingers f f After the burrfeeding movement of the slide h the stud 0 passes by and releases the lever a whereupon a spring, k forces said lever in the opposite direction and causes it to force the slide If back to the position shown in Fig. 9, its recess again receiving the bottom burr in the reservoir i The operation of the machine above described is as follows: The superposed layers of material to be riveted-such as the ends of a piece of belting-are placed on the work-ta ble, and the burr-holding sleeve, having a burr inserted between its spring-fingers,is depressed and caused to bear upon the upper surface of the work, thus holding the latter in position on the worktable. The awl or punch then rises and perforates the work, the hole coinciding with the hole in the burr held by the fingers f f. After the awl recedes, the anvil, having a rivet between its jaws, is moved horizontally until the rivet stands exactly under the hole in the work. The anvil is then raised by the slide j, the shank of the rivet being thus inserted in the hole in the work and in the burr. Vhile the anvil is raised, the hammere descends and upsets the end of the rivetshank, thus uniting the rivet and burr. The anvil is then lowered and drawn back, and the slide 0 having the burr-holding sleeve, is raised, its offset lower end bearing against the ham mer-slide (I and raising the latter. The hammer'slide is engaged by the latch p and thus retained in its raised position. A burr is then inserted between the fingersf f' of the burr-holding sleeve, and a rivet is transferred to the anvil and held by the jaws h h, and thus the operation is continued.

It will be seen from the foregoing that the rivets are presented with their points upwardly and inserted from the under side of the work, the burrs being on the upper side. The operator is therefore enabled to see whether each rivet is properly engaged with a burr without the necessity of turning the work over and looking at its under side, as is necessary when the rivets are inserted from the upper side of the work, as heretofore. To cause the rivets to pass properly from the hopper 0 into the inclined portion of the racewayp, we provide at the upper end of the latter an agitator consisting of a rotating shaft, 2', journaled in suitable fixed bearings and provided with an enlargement in which are set a number of pins, j, which stand in planes at right angles to the axis of the shaft '6, and may be arranged as clearly shown in Fig. 13. The agitator is arranged over the inclined lower portion of the hopper, and is rotated in the direction indicated by the arrow in Fig. 13 by a belt running from a pulley, k", on the shaft 6' to a pulley, F, on the shaft '5, Fig. 1. The arrangement of the pins j is such that a rivet cannot pass down the inclined portion of the hopper under the agitator unless it rests on its head, with its shank projecting upwardly, as shown in Figs. 13 and 15.

A partition, m under the agitator divides the passage through which the rivets pass u it der the agitator into two parts, each of which is of sufficient width'for the passage through it of one rivet at a time.

shaped plate, 1), having teeth projecting over' the side of the agitator next to the reservoir, prevents the rivets from getting caught between the pins 3' and carried out of the receptacle by the rotation of the agitator.

We prefer to make the heads of the rivets overlap each other in the horizontal portion of the'raceway, as shown in Fig. 15, so that they will be closely packed and will not be likely to be displaced. To this end we secure a spring, 0 to the raceway, the free end of said spring projecting over the channel in the raceway and being formed to bear against the upper ends of the rivets and tip them and cause their heads to overlap, as shown, the riv t-head-supporting surface of the raceway being provided with a recess, 20 which facilitates the overlapping of the rivet-heads.

We prefer to provide the machine with a work-feeding lever, g pivoted at 1' to an car on the goose-neck, and having a foot, 8 jointed to its lower end and bearing on the Work. The upper end of said lever bears against the periphery of the disk 42 and is moved intermittingly by a cam, t on said disk, and is thus caused to feed the work. The feeding-lever may be arranged to bear against either side of the disk if instead of against its periphery, in

which case the disk would be provided with a cam, t, on the side against which the feed-lever bears, and would oscillate the lever at right angles to the direction in which it is oscillated by the cam i It will also readily appear that the settinghammer may be forced down by other means than by the spring f. It will also be observed that by arranging the awl or punch and the rivet inserting anvil below the work and the upsetting device or hammer above the work, feeding the rivets in an inverted position to the anvil below the work, and providing independent devices for operating the awl or punch and the anvil so that they may be interchanged and operated in quick succession, we are enabled to perform the entire operation of punching, inserting the rivet, and upsetting the end of the rivet during one rotation of the driving-shaft of the machine, the punch and awl acting alternately in quick succession to form a hole and insert a rivet therein during a part of a rotation of the driving'shaft, while the upsetting-hammer acts to upset the rivet during the completion of said rotation.

The rapidity of operation resulting from the arrangement just indicated is the chief advantage of our invention, although the capability of seeing the burrs on, the upper side of the work previously referred to is also a veryim- The agitator stirs the rivets that gravitate against it, and such porlant advantage secured by the described organization of the machine.
